I got a crash in the following circumstances:
* Launch Xephyr with a xterm client (startx /usr/bin/xterm --
/usr/bin/Xephyr :1).
* It crashes when this exact xterm disconnects.
* Before that, I can start/stop other clients from the first xterm
without crashing Xephyr. Only the first xterm seemed to matter.
